OFDMA, Orthogonal Frequency Division Multiple Access is a broad band communication method. Here channel estimation is more crucial. Based on the FFT size used for OFDM transmission method that many number of channel co-efficients are to be estimated and received signals are to be equalized using this co-efficients. Various methods trying to improve the performance and fastness are proposed. As part of master thesis various methods have be studied and evaluated using the WiMAX 802.16 system.

今年上半年我为现公司一款流量计产品编写的上位机Modbus通讯程序（下位机程序也是我用C编写的，由于受到法律许可限制，在此不能上传，不过在将来我会把设计思路传上共享），包括自创的Modbus协议的Delphi实现及其完整调用，还有一份我编写的该产品的完整的Modbus协议说明书，非常有参考价值。-First half of this year the company I am now prepared a flowmeter products PC Modbus communications procedures (the procedures are under-bit machine I use C prepared, because of license restrictions by law, can not upload here, but I will in the future design ideas Chuan-share), including self-Modbus protocol Delphi to achieve their full call, there is also a preparation of the product I am a complete Modbus protocol specification, a very good reference material.

应用背景实现串口通信基类，和扩展类，可以方便的实现串口通信。在基类上扩展了两个应用类，对于两个应用类实现相应通信协议的解析关键技术应用到了串口通信技术，RS232，并且对于实际应用进行了协议解析。通过基类的继承可以实现其它串口通信协议的解析与通信。很好的封装了串口通信应用。利用多线程技术实现了收发数据。
